. Description.

seen in the drawings, a conveyer constructed in accordance with the .present in-v porte'd and carried .on wheelsv 15. The wheels 15 are' mounted on an axle 16. The

axle 16 is mounted in bearings `extended The 181 .at theirbase and secured by pins eX- f` tending through the perforations 19. The

- p'erforations 19 are arranged to permita 4 vertical adjustment of the standards 18 and the conveyelirame" supported therebfi.

yThe belt conveyer frame is mounted on a supporting bracket comprising a pair of vert-ical standards 18, 18v secured to the belt conveyer frame at a point adjacentl its longitudinal center and between its center of gravity'andl its discharge end, a cross bar 181 provided between the standards 18` and below the conveyer' frame and a pair ot struts or bars 21 extendingfrom the flower ends of the standards 18 to the conveyer frame at a point adjacent its receiving end. I prefer to secure the standards 18 and the struts 21 to the conveyer frame by means of counterpart socket members 201 and 202` respectively mounted on pins or cross bars 20, 2l)3 respectivelyl in the frame. i

The ends 22 of the bars'21 are tubular to act as sockets for lifting handles 23. The

handles 23 are detachably secured to the ends 22 and are employed to permit an at'- tendant or operator to lift. the receiving end of the conveyer.

The conveyer frame normally rests on its receiving end'and is supported in anin clined position on the wheels 15, the standards 18 heilig secured to the frame at a point between its centerof gravity and its discharge end.

The wheels 15 are so placed that when the lower end of the conveyer frame is raised, the center of gravity of the eonveyer frame is disposed substantially in line with the axle 1G, or, in other words, the total weight of the conveyer is poised on the carryin wheels 15.'

l hen the conveyer is actively disposed, the handles 23 are withdrawn from engagement with the socketed ends 22.

The frame or housing of the conveyer, as best shown in Figs. 1- and 3 of the drawings, is constructed of angle bars 24 and 25. These bars extend the full length of the frame and are held in parallel spaced relation by braces 26 and cheek plates 27. The

plates 27 operate to'preven't coal or other material being handled by the conveyer from passing to the inner side thereof to'be deposited on the under or inner side of the conveyer belt 28. The conveyer belt 28 extends lengthwise of the frame formed by the angle irons 24 and- 25, and is supported mainly by the drums 29 and 30. The drum 30 is an idler and is located between a'shoe plate Bland a flexible apron 32. The drum 29, as shown best in Fig. 2', has bearings in sliding blocks 33. To adjust the blocks 33 is-the function of the feed screws 34, which engage the blocks 33 to move the same lengthwise of and in guided relation to. th angle bars 24 and 25.

's best seen in Figs. 3 and 4 of the drawings, the central section of the belt 28 is supported by rollers The rollers 35 have pintle journals for which are provided bearings in the supporting vrails 36. :The 'outer edges ofthe belt 28 overhang and rest upon the rails 36, which maintain the edges of said belt in fixed and close approximation to the lower edge of the cheek boards 37 and prevent sagging 'of the edges of the belt between the rollers 35. The belt 28 is suitably provided at intervals with cleats 38. The cleats 38 are preferably constructed ofrubber. As seen best in Fig. 3 of the drawings, the cleats 38 extend above the belt 2 8 and between the cheek boards 37. The cleats serve in the active ractice of the conve-yer, tomaintain the 'elt 28 in alinement and to impart vibration to apron 32.

The belt 28 is continuous and extends over fthe drum 29, which is driven-by means of therewith.

'the end oppositethe pivot 51 to receive a 39 by a driving belt or chain 41 and trans-1* missionsprockets 43 and jack shaft 42. The plates 27 and 3l, and nosing 44 ,form a boot for the conveyer which prevents the interference by the material being. handled, with the 'underside of 'the belt where the same turns around the drum 30.

The nosing 44 is rigidand is xedly connected with the apron 32. The apron`32. rests over the lower end of thel belt 128,'`

bridges the space between the nosing vand.;

the belt and accommodates the actionv of the said belt and of the cleats 38 mounted thereon. Through the agency of the apron132 and the' vibration imparted thereto bysaid cleats the coal or other material being handled is agitated and spread :prior to being delivered to thebelt 28, to be conveyed to the delivery end thereof. The agitation referred. to as being imparted through-'the agency of the apron 32, is augmented by a tappet ca'm or eccentric 45 mounted at theA end of the shaft bea-ring the drum 30, and

ext-ending beyond the plates 27. The cam 45, as seen best in Fig.` 5 of the drawings, is employed in conjunction with a pintle bar 46. The pintle bar 46 in: the present construction is usually formed from one of the handle/bars 23. Itis furnished with a pointed end fordriving into the .ground'or i floor over which the conveyer is working. v

The Aoperator havingset thepointed end of the bar 46, moves the bar into the path of the eccentric 45, so that the same engages the said bar as the drum 30 rotates. `It is obvious that the result of such action is to break up any solid formation of the pile being` conveyed, and to force the 4nosing 44 into the pile until the upper stratum thereof rolls upon the apron 32 and belt 28. `k

ln Fig.` 7 of the drawings, a modified form ofthe eccentric is shown, the modification embodying a disk 47, which has an ar-v cuate slot 48. Pivotally mounted on the disk 47, is a bearing plate 49. A perforated boss 5l) extends from the plate 49. The axis of the perforation in theboss 50 cordinates with the center of the slot 48, when the plate 49 swings on the pivot 51 with which it is provided. The boss 50 tightly fits the end of the pintle of the drum 30 to be rotated The plate 49 is perforated at coupling pin 52.' The pin 52 also engages any one of the sockets with which the disk 47 is provided. The sockets 53 are arranged in a line concentric with the pivot -51 and median line of the slot 48. It is evi- 'dent' that the pin 52 is disposed in one or other of the perforations 53, the eccentric arrangement of the disk 4'? is modified rela-A tively to the center of the drum 30. In this manner, provision is made for increasing or diminishing the vibratory action of the disk` 47 on the bar 46, y

In Fig. 8 of the draivings,'a modified arrangement of the eccentric is disclosed. .In this arrangement, an ovate cam 54 is .keyed to the drum 30. The long diameter of the cani 54 is greater than. the distance between the aXisof the drum and the bottom of the shoe plate 31. As a result of this construction, the cam 54 strikes upon they ioor or ground on which the plate 3i is resting and l-ifts the saine andthe coal or other material superimposed thereon.

It will be understood that the employ-v ment of any form of the vibrating devices above described is optional.

To prevent the back flow of the load.

`carried on the belt 28,-there are provided aprons 55. As best shown in Fig. 2 of the drawings, the aprons 55 are pivotall'y mounted on shafts 5G, and in bearings therefor'formed 'in the brackets 57.

Any dislodged "particles that roll baclr from thel belt 28 and above the aprons 55, are prevented thereby from rlling backward to the receiving end of the rtonveyer.

As set forth hereinbefore, the plates 2i' andthe shoe late Blconstitute aconveyer boot. Part o the function of the apron 32 y 4 is topermit any material which might find lodgment Iin the booth and on the apron 32 thereof to escape'to be dislodged or forced upward by the cleats 38.' It is obvious that the apron 32vwill uplift and relieve any pressure from below imparted in the manner indicated. 1

While the cheek boards 37 and supporting rails. 36 operate eiiiciently to prevent any lodgment of particles or the accumulation of grit and dust on the inner side of conveyer is employed,A itis impossible to en'- tirely exclude t 'e particles'of rit land dust. If such material reaches vthe obvious that it will adherev to the -surface thereof and accumulate tothe ultimate-effect that the .diameter of the drum and coating thereon. is increased and the lperfect Working adjustment of the apparatus mighty be destroyed. To avoid this, a scraper `plate 58 is provided..

As seen best in' Fig. 4 of the d'rav'vings,l

'belt 28. yThis serves to remove any' adhethe belt 28 and on thelower reach thereof, in such operations as 'those in Which theA rum 30, it is bolsterV 60, whicln as shown, supports the n a r vms tail end ofthe plate 58. The bolster 6() also supports inclined shelves 61, vvvhicliare'disposed iii receiving relation to the plate 58. The .outer end of the shelves Gl extends 'through openings 62shown' in Fig. 'l lof the drawings. If any material passes the scraping edges of the bolster 60 and the angle iron 59 and finds lodgment on the drum 30, the scraping end of the plate 58 serves to dislodge the same. The4 material thus removed from the drum 30, is drawn., 'I

by the belt 28 over the plate 58 and delivered to the shelves Gl, and in turn is delivered by the said. shelves beyond the plates 27 and outside of the apparatus.

- y Operation.

`When operating with a con'veyer constriicted 'and arranged as above described',

and as shown in the accompanying drawings, an attendant .desiring to move the conveyer, places ythe handles. 23 in the sockets provided in the ends 22 of the bars 2l. The

lower end of the conveyer is then lifted from the ground, when it will be found that the weight of the conveyer is nicely balanced on the carrying `wheeis 15. The cony veyer is then moved to any location and the ,nosing 44 is disposed atthe lower edge of la lpile or dump of material to be conveyed. The handles 23 are then removed and thel kattendant presses the nosing 44 of the conveyer into-the pile, using the bar 46 for vthis purpose. kIf a wagon or other vehicle is to be loaded-from` the drum, the wagonor vel'iicle is brought under the delivery end of the conveyer. The motor 40 is then started.

The attendant using the pinch bar 46 or one of the handlesv 23, as indicated, presses rotv against the cam 45, forcing the nosing 44 VWell under'he dump or pile, where the sur! face materiel will flow to the apron 32 and belt 28 incidentl to the vibrating Voperationl of the eccentric 45, as .above described.

The material of the dump -iiowing as -it does to `the conveyer, is carried thereby overy the head or delivery end of the conveyer,

and deposited in the wagon or` vehicle'.l

and theconveyer brought to rest to await the disposition of4 a, second vehicle at the' Vhen the vehicle has received its comple#l l nient or load, the motor 40 is discontinued iso Claims.
